About this map

The Snake River cuts through the northeast corner of this high-desert terrain, where riparian landmarks like Fruit Island and Dilley Island meet an intricate system of water management. The landscape is defined by the transition from the riverbanks to the uplands, marked by significant elevations such as Elephant Butte and Liberty Butte. A complex network of irrigation, including the Deer Flat Low Line Canal, Opalene Ditch, and Conroy Lateral, highlights the human effort to redirect water across this arid environment.

Evidence of natural water sources is found in several secluded locations like Coyote Spring and Alkali Spring. The topography is deeply carved by drainage features such as Opalene Gulch and Rats Nest Gulch, which lead toward the larger basin. Along the south, distinctive landforms like Shares Snout and Shares Basin overlook the winding Coyote Grade Rd, showing the rugged transit routes through the Owyhee and Canyon county borderlands.
